That thread from someone who has never seen a Commodore 64 in the wild made me think of this.

So, what do you rarely or never see in the wild? I wouldn't count color variants, but model variants are fine.

Rarely:
-TG-16 - I've seen one twice since I started game hunting in 2004, both too expensive. I never see the games either, and when I do, it's usually Keith Courage.
-Sega Master System - I've seen these a little more often than the TG-16, though still not that much.
-Genesis model 3 - I recall seeing this about three or four times tops since 2004.
-Sega CDX - I passed up one for $60 in 2004, and I still regret it a little. The only other one I've seen since then was going for $85.
-Sega Nomad: Since 2004, I've seen four, maybe five of these.

Never:
-Vectrex - Well, I did see one at NWCGE, but I wouldn't count that as "the wild."
-CD-I - See above.
-Neo-Geo AES

What about you?
